Hi I just wanted to add that when my daughter now 5 was diagnosed with CAh, I was warned by her doctors that the steroids they take can causr ’thinning’ of the skin, which can cause severe sun burn very quickly. having said that Alisa has never burned and also has a year round tan. You can see sock marks in the winter. Also ALisa has very salty tears which as mentioned earlier dry leaving a whit residue sometimes.
